During the preseason lottery, 225 permits are available for each day. The application period for this lottery is from March 1 through March 31 (eastern time). Applicants will receive an email with lottery results in mid-April (or can get results online or by calling Recreation.gov). Yosemite is planning on the Half Dome cables being up May 24, 2019 through October 15, 2019, but these dates could change based on weather conditions.
Half Dome Permits for Day Hikers
Permits to hike to the top of Half Dome are required seven days per week when the cables are up (as called for in the Half Dome Plan in order to protect wilderness character, reduce crowding, protect natural and cultural resources, and improve safety). The cables are normally up from Memorial Day weekend (late May) to Columbus Day (early October).
A maximum of 300 hikers are allowed (about 225 day hikers and 75 backpackers) each day on the Half Dome Trail beyond the base of the subdome.
Permits for Backpackers (including Camping in Little Yosemite Valley)
Backpackers—including those who want to spend the night in Little Yosemite Valley—should apply for Half Dome permits with their wilderness permit.
Backpackers beginning a wilderness trip outside Yosemite should apply for Half Dome day hiker permits using the information on this page.
Permits are distributed by lottery via Recreation.gov, with one preseason lottery with an application period in March and and daily lotteries during the hiking season.
Backpackers—including those who want to spend the night in Little Yosemite Valley—should apply for Half Dome permits with their wilderness permit rather than using the process described below.
On each preseason lottery application, people can apply for up to six permits (six people) and for up to seven dates. Applications will only be successful if the number of permits requested is available on at least one of the requested dates. If enough permits are available for more than one of the requested dates, permits will be automatically awarded to the highest priority date, as entered by the applicant. The applicant must specify the name of the trip leader and may specify the name of an alternate. Each person may apply as a trip leader only once per lottery. People applying multiple times as trip leader will have all their lottery applications canceled. Permits will only be valid if the trip leader and/or alternate specified on the permit is part of the group using the permits. The group with trip leader or alternate must be present together at the base of the subdome, where rangers will check for permits. The names of the trip leader and alternate may not be changed once the application is submitted, and their permits are not transferable.
To apply for a permit, visit Recreation.gov or call 877/444-6777 (call center is open from 7 am to 9 pm Pacific time; online requests can be made any time during a lottery period).
